Elon Musk says Tesla is making progress on its electric semi-truck

Tesla still plans to release an all-electric semi-truck and is making progress on that front, Tesla CEO Elon Musk said on Twitter over the weekend.

In a reply to Electrek's Fred Lambert, Musk said Jerome Guillen, Tesla's vice president of programs who is in charge of the Tesla semi-truck project, is making progress on the project. The Model 3, however, remains top priority for the company, Musk said.

Tesla CTO JB Straubel discussed the role Tesla could play in the truck industry at the International Transport Forum in Germany in May 2016.

"I can’t say too much about the new products and the things we are developing, but from a pure technology point of view, everything that we’ve done on vehicles translates directly into trucks," Straubel said at the time. "There’s no reason that today you can’t make a very compelling electric truck."
